In this app note, we will show you how to use the DDRC-88A to apply Dirac Live® room correction in multiple rooms. We will assume that there are four stereo zones to be set up.
Note 1: We recommend that you work through a single room calibration using the instructions in the miniDSP Dirac Live User Manual before attempting a multi-zone setup.
Note 2: You may need to use an active USB extender cable or temporarily relocate the DDRC-88A while calibrating some zones. Please read the full app note before proceeding with a multi-zone setup.
Getting set up[Top]
Start the DDRC-88BM plugin and connect to the processor. Drop down the Display menu and select "Dirac Channels Configuration." Edit this screen to create four stereo zones, as shown here:
On the Outputs tab, rename the output channels. We used "Zone1 L", "Zone1 R", and so on. Go to the Mixer tab and confirm that the columns have these labels. Confirm also that each Dirac channel goes to the corresponding output channel, as shown here:
On the Routing tab, rename the input channels. We used "In1 L", "In1 R", and so on. Route each input channel to the corresponding Dirac channel, as shown here:
The above configuration assumes that selection of the zone(s) being played will be done in the source equipment. Another option is to route a single stereo channel input to the Dirac channels, as shown here:
Zone 1[Top]
Start the DiracLive app from within the DDRC-88BM plugin. At the opening screen, select Zone 1:
Proceed through calibration as described in the miniDSP Dirac Live User Manual to calibrate the two speakers in zone 1. At the final Export screen, select slot 1 and export the filter to it. Here is the result:
Zone 2 and up[Top]
Move the microphone and computer to the room or location corresponding to Zone 2. You may need to use an active USB extender cable in order to connect the computer to the DDRC-88A. Alternatively, move the DDRC-88A to the new location with temporary wiring while running the calibration, and place it back in the installed location after all calibrations are done.
Start the DiracLive app again, but this time select Zone 2 of the DDRC-88A at the starting screen. When you get to the Export screen, again select slot 1 and export the filter to it, as shown here:
Then repeat for zones 3 and 4.
Wrapping up[Top]
In the above instructions, we have used only slot 1 in each zone. There are still three slots available in each zone! You can load filters for different target curves into slots 2 to 4 and select them with the remote control.
That's it for this app note! If you do set up multiple zones with the DDRC-88A, please let us know your experience in our forum.
